Abstract (en)

A control system for a hybrid vehicle (Ve) that accurately determines actual engagement states of clutches (6, 7) to shift an operating mode properly by manipulating the clutches (6, 7). The control system is applied to a hybrid vehicle comprising a first clutch (6) and a second clutch (7). A controller (9) shifts the operating mode from Low mode to High mode by shifting from the Low mode to a fixed mode by engaging the second clutch (7) while maintaining engagement of the first clutch (6), and thereafter shifting from the fixed mode to High mode by disengaging the first engagement device (6) while maintaining engagement of the second clutch (7). After the operating mode has been shifted from the Low mode to the fixed mode, the controller (9) fixes a command signal to shift the operating mode from the Low mode to the High mode to complete the shifting operation to the High mode.
